i i. This invention relates to a'composition'of matter for building material and a building block formed therefrom and it consists 'in the novel features hereinafter described and claimed.

An object of the inventionis to rovide a composition of matter lwhich ma adva tageously Aand economically use a block and having qualities which Awill tenaciously hold stucco and plaster tothe surfaces of the block vwhen the block is laid in a wall. i

A A further object of theinvention is to vprovide a block which'is light in weight and to handle. further objectV of the invention' is to lock maximum tensile strength.

A further object of the invention is to provide a composition which utilizes a practicalreducing the cost of producing the block.

4In the accompanying drawing Figure 1 is a top plan view of-a block formed frommy composition of matso ter.

Figi'ire 2 is a side elevational view of the block. v

Figure 3 is an end -elevational view of the same. l

The composition of matter consists of soft coal cinders, sand and cement. These in e-' `dients are in iX-ed" and are supplied. wit a suitable quantity of water to eifect 'an intimate mixture and tenacious concrete acl- 40 hesion.

The. soft coal cinders 'are first ground whereby they ai'c reduced to grains 4'of approximately uniform size. The grain of the .cinders willretain a certain amount ofthe in t ln t afford anchorage for the cement. The bituinen retained in the rains of the cinders will be suflicient tol Ad waterproof quali` for forets Aare formed by the eva oration o building ties to the comrlisition, toughness and to a limited degree pliability. s..

To form a'block weiY hing about 38 pounds o avoirdupois the ingre ients are 'mixed sub. s ntial y in. thev ollowing `stated proporie', 3 pounds avoirdupois ,'sa.nd. 61/3 pounds avoirdupois, cement.

11/3 vquartsfliqurd measure, w"ta er. A These ingredients are mixed an i e oper- 'ounds avoirdupois ggound bituminous l ation relatin to the construction' and manufacture of t e block is yconducted in .the same general manner as the 4 manufacture of cement concrete block products.

[As illustrated in the drawing', the body of the block 1 is hollow and the'surfaces of the pockets 2 indicated by thedots u on the surfaces of the body of the 'b1ockl ese oclllrt e water from lthe composition uring the moId-,- ing of the block andthese 'pocketsvare lined with the mixed cement and bitumen of the soft coal cinders. These pockets constitute a vast number of minute cavities` to which stucco` and plaster will'cling when applied to the'block in the wall. VThey also afford anchora ecavities for mortar.

The b ockA is provided at its end surfaces rbody are provided with a rvast number of f,

with vertical grooves 3 which are spaced'l from each other and which extend from the lower to the upper side surface of the block. The block is further rovided at its end sur- -ons of mortar when the block is laid in a wall, thus preventing `lateral movement of the block in any direction. The surfaces of the grooves 3 and 4: are also provided with pockets 2 which serve as-additional an' choz-age cavities for the mortar.

Having vdescribed the invention, what is claimed is faces' with horizonta groovesfi located bel 1. The composition of matter forbuilcling 'i blocks consisting of proportions .by weight of -groundffvsoft'coal cinders `to the quantity' 5 parts.

of approximately 19 parts, sand to the quana uniform size' in the quantity of approxitity of approximately 12% parts, cement to mately 19 parts, sand in the quantity of apthe quantity of approximately 817/3 parts, proxmately 12% parts, cement in the quan,- water to the quantity of approximately 2% tit-y of approximately 6% parts, and water in the quantity of approximately 2% parts.
